Temperature prediction in air drying of food materials: a simple model

The problem of one‐dimensional heat and mass transfer in infinite slabs during drying of porous solids is considered. Assuming a known distribution of moisture and temperature, it is possible to estimate effective thermal and mass diffusion coefficients in solids. In this paper it is demonstrated th...
